Description

1-OCOL as herbicide application
Technical field
, can efficient, nontoxic, nothing the invention belongs to technical field of pesticide there is provided application of the 1-OCOL as herbicide The Weeds in Turf grass of residual, farmland weed, garden weeds.
Background technology
In many countries such as China, the U.S., green, the safety of crops are received more and more attention.And herbicide As a kind of efficient servicing unit, considerable effect is played in cultivation management and the yield lifting of crops.But Existing herbicide, mostly tanginess, inconvenience are applied to human settlement, and easily remain, and people and animals can be caused harm.
1-OCOL, English name 1-Octen-3-ol；3-Octenol.Also known as mushroom alcohol (Mushroom Alcohol), vinyl amyl carbinol (Vinyl pentylcarbinol) or 1- vinyl hexanol (1-Vinyl hexanol). Molecular formula is C8H16O, structural formula is CH2=CHCH (OH) CH2CH2CH2CH2CH3.1-OCOL is aliphatic unsaturated alcohol, Outward appearance is colourless to pale yellow oily liquid, with mushroom, lavender, rose and hay fragrance.In nature, it is primarily present in In pennyroyal, thyme and fresh mushroom, belong to natural equivalent spices.The fruits such as banana and berry, beer, pork, river prawn, soybean Deng in numerous food product also it is micro containing.Water is slightly soluble in, the organic solvents such as ethanol are dissolved in.1- is industrially produced by synthesis pungent Alkene -3- alcohol, rather than separate and produce from natural goods.
It is mainly used for modulation fragrance and pharmaceutical raw material：(1) it is used for daily use chemicals and flavoring essence, GB 2760-1996 are defined as Allow the flavorant used.Available for the type essence such as mushroom and Earthy Taste is prepared, artificial essential oil, recombinate essential oil or esters are made Spices.(2) as chemical synthesis raw material, applied to pharmaceutical field；As mosquito attractant, applied to mosquitocidal product.There is not yet There is the report of herbicidal efficacy to it.

Embodiment
Illustrate effective effect of the present invention below by way of Herbicidal Testing Trials.
(1) 1-OCOL germination percentage is tested
First, 1-OCOL concentration is set to 0；2.5ml/L；5ml/L；10ml/L；5 concentration gradients of 20ml/L, often Individual gradient sets 4-5 to repeat
2nd, grass-seed selects：Chinese holly, revolution grass, bermudagrass herb, green bristlegrass
3rd, using method：It is that container carries out experiment to select the circular culture dishes of 90mm, and culture dish bottom is spread into two layers of filter paper, Selection equivalent grass-seed (20) is positioned on filter paper, then adds the reagent of each concentration gradients of 5ml, and control group adds sterilized water.Then Culture dish is positioned in 25 DEG C of insulating boxs and cultivated.
4th, result is counted：The quantity that statistics grass-seed germinates daily, to grow root system as germination foundation, until without new Terminate statistics after germination.It the results are shown in Table 1- tables 4.

From result, in 1-OCOL concentration >=2.5ml/L, iron wire grass-seed germination percentage is severely impacted. When concentration is 10ml/L, compared with control group, 1-OCOL reaches 91.4% to the inhibiting rate that bermudagrass herb grass-seed germinates； When concentration is >=20ml/L, the germination of bermudagrass herb grass-seed can be completely inhibited.
(2) 1-OCOL Herbicidal Testing Trials
First, 1-OCOL concentration is set to 0；2.5ml/L；5ml/L；10ml/L；5 concentration gradients of 20ml/L, often Individual gradient sets 4-5 to repeat
2nd, grass seed selection：Chinese holly
3rd, using method：1st, each small basin sowing equivalent grass-seed, pours a certain amount of water, grass-seed germinates after 3-5 days, treats daily It is average long to 5cm it is high when, random selection flowerpot packet sets concentration gradient to test；2nd, each flowerpot pours each concentration ladders of (spray) 15ml Spend reagent.
4th, result is counted：1st, image statisticses：Using weed growth situation is before photographed to record, control group is clapped daily after With the growth differences situation of experimental group weeds；2nd, data statistics：Statistics applies preceding average plant height and strain number with after administration per basin. Continuous statistics one week.It the results are shown in Table 5-6, Fig. 1-2.
The 1-OCOL of table 5 is poured to Chinese holly preventive effect
Wherein：Strain number (unit：Strain)；Plant height (unit：cm).
The sprinkling irrigation of the 1-OCOL of table 6 is counted to Chinese holly preventive effect
Wherein：Strain number (unit：Strain)；Plant height (unit：cm).
Pour or spray it can be seen from Fig. 1-2 after 5ml/L 1-OCOLs 24h, experimental group and control group Chinese holly Growing way occurred as soon as obvious difference, experimental group Chinese holly root occurs rotten situation, causes it to lodge, growing way It is weaker, after 3 days, the substantially all death of experimental group Chinese holly, and then growing way is vigorous for control group Chinese holly.
From result, in 1-OCOL concentration >=2.5ml/L, Chinese holly growing way is severely impacted.Using 2 The average plant height of its plant and control group significant difference after it, after 5 days, using 1-OCOL Chinese holly largely or entirely It is dead.
